4.9 Using the Four Arithmetical Operation Function

Explanation

Four Arithmetical Operations Function

Displays the following computation results on display C. “ ” is displayed at the front

when the computation results are being displayed.

: A

−

: A

A, B indicates display A, B respectively.

Note

•

The meanings of the displayed symbols are as follows:

(Addition)

−

(Subtraction)

(Multiplication)

(Division)

: ^ (Exponent)

•

If the display A function is displaying INTEG TIME (elapsed time of integration), the

computation result displays “- - - - - -” (no data).

•

If the value of display B function is less than 0.0001% of the rating, the computation result

displays “- - oF - -”.

Application Example

: Displays the result of display A

display B.

Computation example: This function is valid when display A is set to some function

other than VA (apparent power) and you wish to display VA on
